System Operation - Exterior, Heated
On vehicles equipped with rear window defrost, the heated exterior mirror glass operates when the rear defrost system is activated.
The heated mirrors are heated for a period of 10 minutes when the engine is running and the defrost system is activated.
The LH and RH heated exterior mirror glass voltage is supplied by the rear window defrost relay through BJB.
If equipped, the rear window defrost can also be commanded on and off by touching the rear window defrost button located on the touchscreen interface (FDIM). For additional information on voice or touchscreen commanded features, refer to the Owner's Literature.
